Answer:

5a. 4w+24≤100

5b. Dimensions=31ft x 19 ft

      Area = 589ft²

Step-by-step explanation:

l=w+12

p=2l+2w

p=2(w+12)+2w

p=2w+24+2w

p=4w+24

The farmer has 100ft of fencing, so maximum that the perimeter (p) can be is 100, meaning (4w+24) has to be less than or equal to 100:

4w+24≤100

For the largest possible perimeter, all 100 of fencing will be used, so allow 100 to be equal to 4w+24)

100=4w+24

4w=76

w=19ft

l=w+12

l=19+12

l=31ft

The dimensions are 31ft x 19ft.

Area=lw

=31*19

=589ft²

Given f(x) = x − 7 and g(x) = x2 . Find g(f(−1)).
ivann1987 [24]

Answer:

64

Step-by-step explanation:

g(f(-1)) can be found by first finding f(-1) then taking that result and putting it into the function g.

f(-1) means we are going to take the expression x-7 and evaluate it for x=-1:  

-1-7

-8

So f(-1)=-8.

So we have this so far:

g(f(-1))=g(-8)=(-8)^2=64.

g(-8) was found by replacing x in x^2 with -8.

A sample of blood pressure measurements is taken for a group of​adults, and those values​ (mm Hg) are listed below. The values a
scoundrel [369]

Answer:

1. coefficient of variation(systolic) = 13.88%

2. coefficient of variation(diastolic)  = 16.2%

3. The coefficients of variation for each data set are within 5 percentage points of each other Therefore  the systolic measurements vary signifcantly less than the diastolic

Step-by-step explanation:

1.  Mean of systolic = ( 117+126+158+96+157+122+116+134+127+122)÷10

      = 127.5

Standard Deviation of systolic = (((117-127.5)^2 +(126-127.5)^2+(158-127.5)^2+ (96-127.5)^2 + (157-127.5)^2 + (122-127.5)^2 + (116-127.5)^2 +(134-127.5)^2 +(127-127.5)^2 +( 122-127.5)^2) ÷ 10)^(0.5)

 SD = 17.7

coefficient of variation(systolic)

= Standard Deviation of systolic /mean of systolic

= \frac{17.7}{127.5} * 100

coefficient of variation(systolic) = 13.88%

2. Mean of diastolic = ( 80+77+76+51+90+89+60+64+72+83) ÷ 10

   = 74.2

Standard Deviation of diastolic  = (((80-74.2)^2 +(77-74.2)^2+(76-74.2)^2+ (51-74.2)^2 + (90-74.2)^2 + (89-74.2)^2 + (60-74.2)^2 +(64-74.2)^2 +(72-74.2)^2 +(83-74.2)^2) ÷ 10)^(0.5)

 SD = 12

coefficient of variation(diastolic)

= Standard Deviation of diastolic /mean of diastolic

 = \frac{12}{74.2} *100

coefficient of variation(diastolic)  = 16.2%

3. The coefficients of variation for each data set are within 5 percentage points of each other Therefore  the systolic measurements vary signifcantly less than the diastolic
